The incidence of epicanthus is extremely high in Asians. Although many techniques have been introduced to remove the epicanthus, there are still some complications. Herein, we introduced a method involving an incision on the lower palpebral margin combined with a tiny triangular flap for correction of epicanthal folds, which is always performed in combination with double eyelid plasty.
After making an incision, the ectopic medial canthal ligament was removed. The ligament pulling the medial canthus was cut along the lower palpebral margin incision, so the medial canthus could be repositioned upward. The tiny triangular flap of the medial canthus would naturally move downward and cover the lower palpebral margin incision. The skin folds on the lower palpebral margin were trimmed and sutured. After epicanthoplasty was completed, double eyelid plasty was performed using the incision or non-incision method.
A total of 547 epicanthoplasties were performed during the past 7 years. The follow-up time ranged from 1 month to 5 years. Ninety-eight percent of the patients were satisfied with the results of the epicanthoplasty. The scars in the medial canthal area were tiny, the enlargement of the medial canthus was obvious, and the double eyelid line in the medial canthal area was natural and smooth.
The introduced method is simple in design and can preserve the original shape of the medial canthus while widening the palpebral fissure, which is a particularly suitable approach for epicanthoplasty in Asian patients.

内眦赘皮在亚洲人中的发生率极高。虽然已经介绍了许多去除内眦赘皮的技术，但仍存在一些并发症。在此，我们介绍了一种在下睑缘切口联合小三角皮瓣矫正内眦赘皮的方法，该方法通常与双眼皮成形术联合进行。
切开后，去除异位的内眦韧带。沿下睑缘切口切断内眦牵拉韧带，使内眦可向上重新定位。内眦的小三角皮瓣会自然向下移动并覆盖下睑缘切口。修剪并缝合下睑缘的皮肤褶皱。内眦成形术后，采用切口或非切口方法行双眼皮成形术。
在过去的 7 年中，共进行了 547 例内眦成形术。随访时间为 1 个月至 5 年。98%的患者对内眦成形术的结果满意。内眦区的疤痕细小，内眦增大明显，内眦区的双眼皮线自然流畅。
介绍的方法设计简单，在扩大睑裂的同时能保留内眦的原有形态，特别适合亚洲患者的内眦成形术。
